Feeleing nervous for college

I have a hard time making friends and meeting girls. Whenever I try to talk to people, I either get a friendly response (as an aquaintance, rather than friend/boyfriend) or get shot down and ignored. Whenever I try to ask someone out (guy or girl), I get rejected for summer classes or too busy with work. But, in their spare time, they go out with friends that they already know, but not me. I don't know what to do. I don't get invited to parties, nor did I have a prom date. I felt really sad and depressed and even worthless, which caused my grades to lower. I feel I'm missing out by not having more friends (I have a solid group, but enjoy meeting new people. Only one girl is in my group, so I'd love to meet girls too). I had crushes on many girls, but never even got to be friends with them, since they cliqued with their friend circles / boyfriends, or were too busy. Same thing happened with guys. I constantly get the feeling that i'm unwanted by others. NO girl takes interest in me, even as a friend. How do i find a group of friends to go out with and have college style experiences when i go to college in fall? If i can't even make friends, how will I get a girlfriend (not a priority at the moment)? My only hobbies include video games and movies, working out at the gym, reading the news, and playing basketballI found many cultural clubs to join, like Muslim/Japanese/Filipino/Outdoors clubs. Even found a co ed and cheap frat that is a good way to mingle (they even have parties and formals!) I also have severe social anxiety (around strangers), but it cools down with people I know or open minded people. I don't want to graduate college without good friends/kissing a girl/good gpa/l? (I'm 18 btw). And will being Indian be a turn off? I'm depressed now, no free therapy in Bay Area
